Abstract:
An electroantennogram (EAG) technique compared the antennal olfactory responses by both sexes of eight Japanese Papilio species with known host plants in laboratory experiments. Papilio species were collected from Honshû and Kyûshû (Japanese islands). The behavioral responses to volatile leaf substances from Citrus deliciosa, Zanthoxylum ailanthoides, Phellodendron amurense, Orixa japonica, and Foeniculum vulgare were examined in laboratory experiments. Individual EAG reactions were recorded. The results were very similar to the empirical field observations. The electrophysiological results of both sexes showed that the volatile substances released from non-preferred plants mainly elicited more significant EAG responses than the volatile substances from preferred host plants. Moreover, we performed behavioral experiments using eight female butterflies and their responses to five host plant species. An association between host plant selection behavior and taxonomical classification exists within the Papilio genus. The EAG responses were small when exposed to the plants with high scores in the behavioral experiments. Host plant preference patterns seem to be related to the volatile substances within the host plants. The butterflies responded to Linalool in both the behavioral and electrophysiological experiments.
摘要:
在实验室实验中,一种电触角图(EAG)技术将八种日本Papilio物种的两性的触角嗅觉反应与已知的寄主植物进行了比较。Papilio物种是从Honsho和Ky这两项(日本岛屿)收集的。对柑橘叶挥发性物质的行为反应,花椒,黄柏,Orixajaponica,和Foeniculumvulgare在实验室实验中进行了检查。记录各个EAG反应。结果与经验现场观察非常相似。两种性别的电生理结果表明,与首选寄主植物的挥发性物质相比,非首选植物释放的挥发性物质主要引起更明显的EAG反应。此外,我们使用八只雌性蝴蝶及其对五种寄主植物物种的反应进行了行为实验。在Papilio属中存在寄主植物选择行为与分类学分类之间的关联。在行为实验中,当暴露于具有高分的植物时,EAG反应很小。寄主植物偏好模式似乎与寄主植物内的挥发性物质有关。在行为和电生理实验中,蝴蝶对芳樟醇都有反应。
